Identify which of these types of sampling is used: random, systematic, convenience, stratified, or cluster. To determine her body temperature, Charlotte divides up her day into three parts: morning, afternoon, and evening. She then measures her body temperature at 3 randomly selected times during each part of the day. What type of sampling is used?

Systematic sampling

Explanation:

Systematic sampling involves selecting individual items from a group at a random starting point and takes additional items at a standard interval, called the sampling interval. So based on how that she had first of all divided the day into  morning, afternoon and evening before randomly selecting each part  of the day, the sample method used is definitely systematic sampling.
